Name of the Vulnerable Software and Affected Versions
Nezha versions 1.0.0 through 2.3.14
Description
A memory exhaustion issue exists in the dashboard file manager WebSocket endpoint. The
fmStream function fails to call SetReadLimit, which allows message sizes to remain unbounded. Authenticated users with file manager permissions can exploit this by sending a single oversized binary message to the '/api/v1/ws/file/:id' endpoint, leading to an Out-Of-Memory (OOM) kill that terminates all agent monitoring.Recommendations
Update to version 2.3.15 or later.
